OK heres the deal. Dec 21, 2012--the day that the Mayan calendar comes to a very abrupt end. Lots of speculation on this. There are a number of theories about what is going to happen on this day. I will start with the most popular first:
1. On this day the earth, the sun, and the exact center of the galaxy will be in perfect alignment. There is no doubt about this as it has been scientifically proven. The question is, how will this affect us? Some scientists say, since the discovery that there is a black hole in the center of every galaxy, that the gravitational strain of this alignment will demolish the magnetic field around the earth, thus destroying our atmosphere. The effects of this would be cataclysmic. No more oxygen (or any gas for that matter),also no more protection from the harmful radiation of the sun.
2. Sun storms---The sun changes its rotation every 11 years. The most violent sun storms occur every 2nd rotation shift. So basically every 22 years the sun has some hellacious sun storms, or solar flares. This has been happening since the suns birth, so no big deal right.....wrong. The next cycle in the suns rotation is due in Dec 2012. The reason this time is different, and that we have never been effected before is once again due to how the Earth and sun are lined up. Never before have we taken a direct hit from a solar flare, but this time we will. The spot on the sun that will produce these storms will be in exact alignment with Earth. Think of it like this: prop a globe on a post and shoot at it with a 12 gauge birdshot, it will not be effected every time, but it only takes one good hit to really fuck it up. Scientists theorize that this direct hit from a solar flare will spin the earth so severely that Europe will be located at the equator when it is over.
3. The Mayan calendar----This was and still is the most precise calendar ever invented by man. In fact to this day, it is even more accurate than the current calendar in use. The Mayans believed that time is cyclical, and not linear. In other words things repeat themselves in cycles. There are three stages to it; the first has a cycle of 266 days, the second has a cycle of 365 days, and unfortunately I cannot remember the third. Anyway, the Myan calendar is based off of a cycle that starts over every 5125 years. This is the time it takes the Earth to complete one full "wobble" on its axis. Now the Mayans say that on this day our gods will return to earth to collect and mine more resources for their planet. Even now, in the last few years, when the sun sets on the Mayan temples, the shadow that is cast upon the temple is that of a serpent descending from heaven. They even put snakes heads at the bottom of the temple stairs to coincide with this. Even though I am a firm believer in aliens, I don't think this will happen. I think the Mayans just had a very sophisticated sense of astronomy, and once the Earth completes its wobble, the whole process just starts over again.
